UNITED STATES PATENT orrrcn EDWARD JOHNSON, OF LOUISVILLE, KENTUCKY.

TOBACCO-PRESS.

Application filed January 6, 1908.

To all whom it may concern:

Be it known that I, EDWARD JOHNSON, a citizen of the United States, residing at Louisville, in the county of J eiferson and State of Kentucky, have invented a new and useful TobaccoPress, of which the fol lowing is a specification.

This invention relates to presses of that type employed in the manufacture of plug tobacco, and has for its principal object to simplify and improve the construction of the press and to eliminate many of the movable parts which have heretofore been considered essential to practical operation.

In the majority of presses of this general class, the compression chamber is formed of a number of movable parts, including a movable front wall, and a pair of movable side walls, all of which are forced inward in order to act 011 the sides and ends of the plug during the compressing operation, a vertically movable plunger being ordinarily employed to effect the main compression.

The number of movable parts makes it a matter of difficulty to keep the machine in good repair, owing principally to the great wear which occurs in the cams and similar mechanical elements employed in effecting movement of the various parts.

It has been found in practice that the machine may be simplified without any decrease in the value of the product by making the side walls practically rigid, and employing only the movable front and the compression plunger.

In the accompanying drawings :Figure 1 is a plan view of a tobacco press constructed in accordance with the invention. Fig. 2 is a detail perspective view of one of the side walls of the press, detached.

Similar numerals of reference are employed to indicate corresponding parts throughout the several figures of the drawings.

The various parts of the press are mounted on a suitable frame including a table or bed 1 that is provided at the rear edge with a vertically disposed flange 2, that forms the rear stationary wall of the compression chamber.

To the flange 2 are secured the side walls of the compression chamber, each of these being in the form of a plate having a pair of webs 34, arranged at a right angle to each other, the webs 3 forming the sides of the compression chamber, while the webs 4 Specification of Letters Patent.

lie flat against the bed or table and are provided with openings for the passage of securing bolts 13. Extending from the rear ends of these webs is a flange 5 that is formed integral with both webs, and serves to stiffen and reinforce the structure. This flange is provided with an opening for the passage of a suitable securing bolt which, also, extends through an opening formed in the stationary rear wall 2 of the press, so that the bottom, the rear wall, and the two side walls are all permanently and rigidly secured together and serve mutually to strengthen and reinforce each other.

In order to permit the ready introduction .of the tobacco into the compression chamber, the forward portions of the upper edge of each of the webs 3 is flared outward, as indicated at 6, the degree of inclination gradually reducing from the extreme forward ends of the webs in the direction of the flange 2. These flaring portions will permit the introduction of the previously booked and wrapped tobacco in the chamber in position to be acted upon by the vertically movable compression plunger, (not shown).

The front wall 7 of the press is movable toward and from the flange 2 and is carried by a suitable slide, and actuated by a toggle mechanlsm comprising arms 8 and 9 connected by a link 10 and cooperating with a block 11 that slides in guides formed in the table 1.

In operation, the tobacco is introduced into the compression chamber, the flaring side walls serving to partly compress the tobacco in the direction of the length of the plug, so that the tobacco will completely fill the cross sectional area of the compression chamber. The toggle mechanism is then operated, and the front wall of the press is moved rearward at the same time that the main compression plunger is forced down.

I claim A. press comprising a horizontally disposed chamber, a vertical abutment wall arranged thereon and forming the fixed rear wall of the compression chamber, a reciprocatory plunger having a work facing sur face parallel with said wall throughout the length of its stroke, binary side walls each formed from a plate having a vertical web, the upper edges of the forward portions of said webs being flared outwardly, each of said plates having a horizontally disposed web coequal in length with the lower portion 01 the vertical Web, each of said plates hav- In testimony that I claim the foregoing as mg a vertically chsposed flange formed mtemy own, I have hereto aifixed my signature 10 gral with the vertleal and horizontal Webs 1n the presence of two wltnesses.
